CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit to provisional patent application Ser. No. 60/717,947, filed 16 Sep. 2005, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to mailboxes, and more particularly to a mailbox that is designed to withstand the impact from snow, slush, ice and water thrown from a plowblade when streets are being cleaned in the winter time, as well as impact from vandalism.

2. Description of Related Art and Comments re Comparison the Invention

Below are comparisons and opinions to some mailbox patents found in a patentability search for the spin post and protective shield:

Webber vs. Gay The Post:

GAY: The Gay design has a vertical square post. This has been proven through the years to be much more vulnerable than the round type post, especially on a slant. The wood post into a concrete footing is a permanent but temporary installation, the wood would eventually rot and there would be no way to adjust it. In addition, the patent clearly specifies that this support post must be perfectly vertical for the device to function properly.

Invention: The round angled stainless steel post is much less vulnerable to a hit and would last approximately fifty years. With the easy install anchoring system, one can adjust by loosening the three base nuts and shimming it with ordinary washers.

The Box To Post

GAY: The clamp on post design is also very temporary, when the wood shrinks the clamps will loosen. The clamping U-bolts would need to be a non-corrosive type material allowing periodic tightening. This would also make this mailbox easy to steal.

Invention: The spin post shield and box holder is a formed three sixteenth inch stainless steel, welded and fastened with a half inch diameter nut and bolt through the bearing, making this part much more durable.

The Mail Box Support Arm

GAY: This portion has many parts mostly for extending the box towards the street and allowing adjustments just by a few inches. The shear pin bolts seem to be light duty. There would need to be an access hole to the pin nearest the bearing allowing moisture into the bearing eventually seizing. The bell shape space around the bearing could also be a potential home for bees.

Invention: This portion has one part, the mounting base and shield. This very ridged piece connects and protects the side and underside of the box, fastened as described above.

The Swing Concept

GAY: This design allows the box to swing when hit and returns to it's original position. However, it only rotates on the same side of the post spinning upside down. The Gay design keeps the box in the most vulnerable position for damage. The unprotected mailbox would most likely be just as damaged as a fixed type box. If the door could not be closed or if it were left open the angle the box turns, moves the door into a tear off position. The combination of area with the extended support arm would transfer back to the wood post that must remain “perfectly vertical”.

Invention: The spin post design allows the box to spin three hundred and sixty degrees around the post and as far out of the way as possible. The initial force pushes the box away exposing the least amount of area (the back side).

The invention provides a very strong frame from the ground up and reduces all the pressure points as much as possible.

Webber vs. Black Overall

BLACK: This design does not return to it's original position and is as temporary as any vertical wooden post. If it were pushed out of plumb then the box would face that direction. The post and box holder has much more area receiving the pressure. Ice would form on the flat horizontal and the vertical post area preventing any pivoting at all. This design should does even compare to the present invention.

The universal flex joint assembly is coupled to the bolt or rod.

BEST MODE OF THE INVENTION

FIGS. 1, A, A1, A2, A3: The Spin Post Mailbox Design

FIGS. 1, A, A1, A2, A3 show a new and unique spin post mailbox design according to the present invention. As shown in FIG. 1, the present invention provides a mailbox arrangement featuring, in combination, the mailbox 3; a pipe 2 for coupling and/or affixing the mailbox 3 to the ground in a desired position for receiving mail, and a swing bearing assembly 100 for coupling the mailbox 3 to the pipe 2. The swing bearing assembly is arranged between the mailbox 3 and the pipe 2 so that its plane of rotating P_(R) is on a slanted axis in relation to the axis of the force of gravity acting on the mailbox 3 for rotating the mailbox 360 degrees or more in relation to the pipe in response to an impact, including that from snow, slush, ice or water thrown from a plowblade (not shown) when streets are being cleaned in the winter time, as well as impact from vandalism, and for returning the mailbox to the desired position based on the force of gravity acting on the mailbox. Embodiments are envisioned and the scope of the invention is intended to include either the longitudinal axis of the pipe 2 being arranged on the slanted or oblique axis in relation to the force of gravity acting on the mailbox and/or the plane of the ground, the plane of rotating of the swing bearing assembly 100 being on such a slanted or oblique axis, or both.

For example, as shown in FIG. 1 a, by way of example, the pipe 2 may be arranged at an angle of about 80 degrees in relation to the plane of the ground, and the swing bearing assembly 100 best shown in FIG. 1 b is arranged in the pipe 2 to rotate in relation to the angle of about 80 degree. Although the invention is described by way of example in relation to an angle of about 80 degrees, the scope of the invention is not intended to be limited to any particular angle between the post and the ground. For example, embodiments are envisioned in which the angle between the post and the ground is less than or more than 80 degrees, including angles in a range such as about 60 to 85 degrees.

FIG. 1 b shows the swing bearing assembly 100 in further detail mounted or coupled between the mailbox 3 and the pipe 2, including a flange bearing mounting ring 5, a welded plate 6, a flange type ball bearing 7, a bolt 8 welded to plate 6, a lock nut 9 and retaining nuts and bolts 10. As shown, the flange bearing mounting ring 5 is coupled to a collar 4 that is coupled itself coupled to the mailbox mounting plate 3′. The welded plate 6 is coupled to the inside of the pipe 2. The flange type ball bearing 7 is coupled between the flange bearing mounting ring 5 and the welded mounting plate 6. As shown, the plane of rotating P_(R) of the swing bearing assembly 100 is substantially perpendicular to the longitudinal axis or circumferential plane of the pipe 2.

Furthermore, the present invention may also include the pipe 2 being arranged at an angle of about 90 degrees (i.e. perpendicular) in relation to the axis of the force of gravity and/or the plane of the ground, and the swing bearing assembly 100 being arranged between the mailbox 3 and the pipe 2 on a slanted axis in relation to the axis of the force of gravity acting on the mailbox. In this case, the plane of rotating P_(R) of the swing bearing assembly 100 is on the slanted or oblique axis in relation to the axis of force of gravity acting on the mailbox 3 for rotating the mailbox 360 degrees or more in relation to the pipe in response to the impact. Moreover, in this case, the plane of rotating P_(R) of the swing bearing assembly 100 would be oblique to the longitudinal axis or circumferential plane of the pipe 2. Similar to the first embodiment, the plane of rotating P_(R) of the swing bearing assembly 100 may be arranged at an angle of about 80 degrees, or possibly in a range of about 60-85 degrees.

By way of example, the flange type ball bearing 7 may be an off-the-shelf extended inner race ball bearing (flange-type) that is well known in the art. As a person skilled in the art would appreciate, it includes a housing or flange, an inner race, an outer race and ball bearings arranged inbetween. As shown, the inner race may be fixedly arranged up against the welded plate 6 and pressed against it by the bolt 8, and the housing or flange may be fixedly coupled to the mounting ring 5. In operation, the outer race may be held by pressure to the housing or flange and allows the mailbox 3 to freely rotate 360 degrees or more in relation to the pipe 2 in response to the impact. Although the invention is shown and described in relation to a flange bearing, the scope of the invention is not intended to be limited to any particular type or kind of bearing. For example, Figure A1 shows an alternative embodiment of the present invention in which a wheel type bearing (see element J) is used. Moreover, the scope of the invention is intended to include other type or kind of bearing either now known or later developed in the future.

As shown in FIG. 1 a, the pipe 2 is mounted at the angle of about 80 degree to a pipe mounting plate 2′ for coupling to the ground. By way of example, the pipe 2 may couple and/or affix the mailbox 3 to the ground in FIG. 1 a using techniques set forth in Figures A2 and A3. Although the invention is shown and described in relation to such techniques in Figures A2 and A3, the scope of the invention is not intended to be limited to any particular type, kind or way of coupling the pipe to the ground. Moreover, the scope of the invention is intended to include other type, kind or ways of coupling the pipe 2 to the ground either now known or later developed in the future.

The swing bearing assembly 100 may also be weatherproof protected by being arranged inside the collar 4, as shown.

The mailbox 3 may also include an optional protective shield (see element B in Figure AC).

Figure B, B1: The Spring Back Mailbox Design

Figures B and B1 show a spring back mailbox design which may be used alone or together with the invention set forth above. It provides a mailbox assembly comprising: a mailbox; a pipe for coupling and/or affixing the mailbox to the ground; and a spring assembly arranged between the mailbox and the pipe for providing resiliency to the mailbox in response to a force intended to vandalize the mailbox.

The spring assembly includes a spring coupled in relation to a bottom plate and a bolt or rod arranged in and coupled to the pipe, as well as a universal flex joint assembly for coupling to the mailbox. The universal flex joint assembly is coupled to the bolt or rod.
